prospec: Skill for Claude Code

.agents/skills/prospec-quickstart/SKILL.md

prospec-quickstart is a skill for Claude Code, Codex from benwu95/prospec. It costs 74 tokens per session (1,491 once invoked), scanned A, original, MIT.

A one-time project onboarding workflow for setting up localized triggers, refreshing agent configuration, and preparing project knowledge generation.

In plain words
What is it for?
Use it to start or repeat onboarding, prepare the knowledge scan, and continue into automatic project documentation.
Why use it?
It removes several manual setup steps when introducing the workflow to an existing project.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is benwu95/prospec's own configuration. It tells Claude Code and Codex how to work on prospec itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything prospec configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

prospec-quickstart scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Prospec Quickstart Skill

Activation

When triggered, briefly describe:

  • That prospec quickstart has scaffolded the project and you'll finish onboarding
  • You'll localize skill triggers to the configured language (when non-English), re-sync agent config, prepare the knowledge scan, then hand off to knowledge generation
  • This is a one-time onboarding flow — it is re-runnable and self-terminating

CLI Prerequisite (required)

The prospec CLI is a required file for this skill — its deterministic steps call prospec commands. Probe BEFORE any other step; there is no manual fallback.

  1. Run prospec --version (Bash).
  2. Command not found / not executable → STOP. Ask the user to install the prospec standalone executable — the one-click installer script from the project README (macOS/Linux install.sh, Windows install.ps1) or a release binary from GitHub Releases; prospec is NOT published to npm. Then re-run this skill.
  3. Version older than 2.10.0 → STOP. Report the installed vs required version and ask the user to upgrade, then re-run this skill.

Hand-executing a CLI-owned mutation is NEVER the fallback — that re-introduces the nondeterministic serialization this contract exists to remove.

Startup Loading

  1. [DYNAMIC] Read .prospec.yaml — artifact_language and skill_triggers decide whether native-language trigger localization runs

Core Workflow

This skill shells out to the prospec CLI (Bash) throughout. The CLI probe is the shared CLI Prerequisite above.

Step 1: Localize Skill Triggers (non-English only, fill-missing)

Read .prospec.yaml. When artifact_language is not English, localize the skills that have no skill_triggers entry yet (the exact gap prospec agent sync names in its hint). This covers both a fresh project (all skills missing) and a project that just gained new skills (only the new ones missing) — so you never delete .prospec.yaml to re-localize:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
